An induction heating furnace (10) comprises an induction coil assembly (16) and a ladle (12) having a metallic shell (14) that supports a crucible holding metal to be heated by the furnace. The ladle (12) is readily separated from the induction coil assembly (16) so that the heated metal may be conveniently and reliably moved among operational stations. The induction coil assembly (16) has a prese...

This "TORSION SPRING PHASE TRANSFORMER" consists simply of a torsion spring, part 3, placed between the camshaft, part 1, and the toothed wheel which transmits motion to it, part 2. It functions as follows: the camshaft 1, during normal operation, encounters a resisting torque due to friction, which increases approximately with the square of the angular velocity. The wheel 2 will tend to rotate on...
